SHUTTLE-PLACER.

To @ZZ whom t may concern.'

Be it known that I, Erm. H. RYoN, a citizen of the United States, residing at TWaltham, in the county of Middlesex and State oi' Massachusetts, have invented a new and useful Shuttle-Flacon of which the follow ing` is a speeilication. Y Y

rl`his invention relates to a device adapted to engage shuttle which has tailed to fully err-ger its shuttle box, and effective to complete the boxing of the misplaced shuttle. Such a device, while capable of general application, is especially useful on a weit replenishing` loom in which correct boxing oi' the shuttle is essential to proper operation of the replonishing mechanism.

lt is the general object of my invention to provide a shuttle placer of an improved and simplified construction, adapted to be supported on a iined part of the loom, and preleralny effective to stop the loom it the shuttle is so far misplaced that it cannot be boxed by the shuttle placer.

ln its preferred form, the shuttle placer comprises a shuttle-engaging head movably mounted on a support which is itself also capable oi movement, the movements of both head and support being yieldingly resisted. When engaged by a misplaced shuttle, the head is moved upon its support and by such movement forces the shuttle into the shuttle box. If the shuttle is too widely misplaced, the head and support move as a unit and actuate the loom stopping devices.

Important features of my invention relate to the design and disposition of the several parts of the device, whereby the desired movement ot' the shuttle is accomplished. Y

My invention further relates to arrangements and combinations of parts herein after described and more particularly pointed out in the appended claims.

A preferred form oi my invention is shown in the drawings, in which- Figure 1 is a plan view of certain portions of a loom with my improved shuttle placer mounted thereon;

Fig. 2 is a detail view similar to Fig. 1, partly in section, and showing certain oi' the parts in a different position;

placer, looking in the direction of the arrow 3 in Fig. l;

Fi g. l is a sectional plan view taken along the line in Fig. 3;

F ig. 5 is a detail sectional view taken along the line 5"-5 in Fig. 4, and

Figs. t3, 7 and 8 are diagrammatic views showingthe operation of the shuttle placer in relation to differently positioned shuttles.

Referring to Fig. 1, l have indicatedl a portion of a loom side 10, a breast beam 11, a lay 12, a shuttle S, and a picker 13, all ot the usual construction. The usual illing fork la is slidably mounted on the breast beam and operates through a lrnocloolf lever 15 to release the shipper handle 16.

lily improved shuttle ilacer comprises a shuttle-engaging head 1 pivoted at 18 to a support or slide 19 mounted for straightline movement in a stand 20. A spring 21 3) within the slide forces the same yieldingly rearward to the 'normal position shown in 1 and 8. A rod 22 (Fig. 3) is secured within the slide and ,extends through a bearing in the stand 20. The spring 21 surrounds the rod 22, which acts both as a guide for the slide and as a support for the spring.

The head 17 is grooved at 23 (Fig. 5) on its shuttle-engaging face, and the body portion ot said'head is slotted to receive a tension spring 2-1 (Fig. 1) connected between the head 1'? and the slide 19. Cooperating stop shouldersv 25 and 26 are formed on the heed and slide respectively, and the spring 241 tends to move the head to the normal position, in which these shoulders engage each other as shown in Fig. 6.

16. As the slide moves forward, the plunger i 27 eventually slips by the engaging corner of the slide and assumes the position shown in Fig. 2. This release ofthe knock-oit lever before the slide reaches its extreme 'forward position permits the slide to return to its normal position, sliding easily the spring plunger without binding.

The operation of my improved shuttle placer is clearly shown in 6, "i and Fig. 6 indicates the relative position oi? the shuttle placer and the shuttle S when the latter has been properly boned and therefore requires no assistance :troni the shuttle placer.

Fig. 7 indicates in dotted lines the position of the shuttle S when it has not fully entered the shuttle box and when in ifaot it is misplaced to the extreme limit which can be corrected by the shuttle placer shown in the drawings, the point oil the shuttle barely entering the `groove 23 in the shoulder portion 17"* oi the head 17 as the lay shuttle move forward. It will be seen that this shoulder portion is disposed to 'the right oi the pivot 18, as shown in 7, and the head 17 therefore tends to swing to the right when engaged by a shuttle in the position shown in Fig. 7. The spring 2li is ol' less Strength than the springl 2i, so that snch movement to the right may more readily occur. As the head 17 swings to the the shuttle is moved thereby te the 'in -l boxed position indicated in full lines in Fig. 7, the point of the shuttle being disposed against the shoulder 17a during such movement, as appears in the drawine',

lf the shuttle not wid-(yy VL)laced and engages the head near its right-hand edge, the head acts as a lined cam to torce the shuttle to position without me" ient on its pivot. A shuttle placer formed a single piece may thus be used to secare some of the advantages of my invention, but its field of action will be limited to small displacements.

In Fig. 8 I have indicated the y of the device when the shuttle is widA is placed. In this case the head 1l' and slide 19 are moved directly forward a unit, en ,gaging the plunger 27 and swingi o; the knock-oil' lever 15 to release the shipper lever 16 and stop the loom. lt will be noted that the forward movement ci? the slide 19 when thus engaged is much greater than the movement of the usual filling iorlr slide which operates the saine knock-oil lever, but such greater movement is permitted by the action of the plunger 27 in slipping; past the edge ci' the slide 19 after a certain movement thereof.

lt will thus appear that l have provided ,i exceedingly simple device comprising` we movable parts by which a shuttle Will be properly boxed unless too widely mis placed, in which event the loom will be stopped.

li'aving fully described my invention, i will be evident that changes and nodiiications can be made therein by those slilled in the art without departing from the spirit and scope thereo'l as set forth in the claims, and do not wish to be otherwise limited to the details herein disclosed, but what l claim isl. ln a loom, a movable support and a shuttle placel mounted thereon and normally at rese, said shuttle placer receiving an an,jlar shuttle positioninp,` movement by engagement with a sriggglit y misplaced shuttle.

2. ln a loom, a shuttle placer normally at rest and receiving; a shuttlepositioning movement only by engagement with a misplaced shuttle.

3. ln a loom, a shuttle placer supported on a fixed part oi? the loom and normally at rest, said placer being movable directly by a misplaced shuttle when engaged ther to correct the position of d shuttle.

l. ln a loom, s, shuttle-en o'fwinpg head and a support therefor, said head be' mounted :tor movement on. said support to bei; a misplaced shuttle, and for movement with said support to stop the loom when engaged by a widely misplaced shuttle.

5. ln a. loom, a stand, a slide yielding j; mounted therein and connected to stop the loom, a head pivoted to said slide, f. stop on said slide, and a spring` normally holding said head against said stop, said head being movable on its pivot when engaged by a slightly misplaced shuttle and having a canL action to bon the shuttle by such movement.

6. In. a loom, a stand, a slide yieldingly mounted therein and connected to stop the loom, and shuttle engaging head pivoted to said slide, said loom stoppingI connectionl beine; disengaged before the completion ot the forward movement oil3 said slide.

ln testimony whereof l have hereunto atiixed my signature.
